Measured with my lab quality wall socket gizmo ($9.95)
----------------------------------------Computer is a homebrew i5/ 4 gig ram/ 2 x 500 gb drives, W7 pro/64 bit/ Zonealarm & AVG. Intel DH61WW mobo Boinc: 100%/ 4 cores = 160 watt 75% /4 cores =120 watt 50% /4 cores= 100 watt Snooze = 86 watt Got any more? CPU temp is 71C at 100% with stock cooler, but only 50C at 75%, which is where I run it. [Edit 1 times, last edit by Hardnews at Nov 9, 2011 5:42:13 PM] |

i5-2500k @ stock settings (3.4 ghz)
----------------------------------------H61 MB 4 GB DDR3 RAM 160gb HD Win 7-64 100%/4 cores = 125 watts at the wall socket (no monitor) i7-2600k/4C/8T @ 4.5ghz Asus Sabertooth P67 4gb DDR3 RAM 120gb OCZ Vertex 3 SSD Nvidia GT430 Win 7-64 @4.5 ghz = 200 watts @4.6 ghz = 235 watts @4.7 ghz = 265 watts All readings taken at the wall socket (no monitor) temps 75-80 C with Coolermaster Gemini II As you can see, it doesn't really make sense to overclock excessively when running 24/7 as you pay a huge penalty with electric and heat  [Edit 1 times, last edit by ryan222h at Nov 10, 2011 4:07:19 AM] |

The overclock i7 figures are indeed interesting. I have an i3 with Linux I'll try and add, but it BOINC is grumbling about using Ubuntu at the moment.
----------------------------------------Cost of UK juice is an issue for me, so it's a toss-up between crunching at 100% for 12 hours, (1920 watts) or at 50-75% for 24. (2400 watts) Running 12 hours at 100% saves about 500 watts per 24 hours, it seems. [Edit 1 times, last edit by Hardnews at Nov 10, 2011 8:15:58 AM] |

I was curious to see how much power I could save on my i5
----------------------------------------So instead of using BOINC to control loading, I underclocked the cpu in the BIOS I decided to set the CPU multiplier to 30x to give a frequency of 3 ghz (no turbo) Here is the figure 3.4 ghz/4 cores 100% = 125 watts at the socket 3.0 ghz/4 cores 100% = 96 watts at the socket This comes out to roughly a 25% decrease in power consumption for 10% less computing power. Hardnews, I noticed your 160 watt consumption is much greater than mine....do you have a graphics card or monitor plugged in there as well? |

What are your voltage settings and do you have LLC enabled?

It's about right for that GPU.

20w with no monitor?

GT430 TDP is 49W, so depends on usage; I'm not exactly sure but I would expect around 10W when the GPU is not being used but up to 40W when the system is in use. A system using around 160W with an i7-2600K @ ~4GHz would be about right (I have one). Up that to 4.5GHz and I would expect at least 180W for the system. Add a GPU and that's about right.

Your power draw and temps seem high for a 2600k @ 4.5 Ghz. What are your voltage settings and do you have LLC enabled? I have all settings on auto on the motherboard. I just set 45x multiplier and disabled turbo. CPU-z reports around 1.32 volts during crunching at 4.5 LCC is set to auto as well so I'm not sure if it its utilizing it or not. 200 watts is with the GPU at idle....with 100% GPU load I'm at 230 watts [Edit 1 times, last edit by ryan222h at Nov 11, 2011 12:26:37 AM] |
